Much of the attention in the field of video adaptation has been directed to the Scalable Video Coding (SVC), which is the extension of the H.264/AVC standard, since the bit-stream scalability for video is a desirable feature for many multimedia applications. The need for the scalability mainly arises from the need for spatial formats, bit rates or power. To fulfill these requirements, it would be...
This work relates to the developing and implementing of an efficient method and system for the fast real-time Video-in-Video (ViV) insertion, thereby enabling efficiently inserting a video sequence into a predefined location within a pre-encoded video stream (e.g., for inserting advertisements). The proposed ViV method enables achieving a significant performance over the conventional brute-force approaches...
In this work we present a novel optimal buffer control approach for H.264/AVC low-delay applications by dynamically allocating computational complexity (such as a number of CPU clocks) and bits for encoding each coding element (basic unit) within a video sequence, according to its predicted MAD (Mean Absolute Difference), while considering buffer size limitations (preventing underflow/overflow of...
In this work, we present a novel approach for optimizing H.264/AVC video compression by dynamically allocating computational complexity (such as a number of CPU clocks) and bits for encoding each coding element (basic unit) within a video sequence, according to its predicted MAD (mean absolute difference). Our approach is based on a computational complexity–rate–distortion (C–R–D) analysis, which...
